To find the unit rate, we need to determine the fraction that represents one item out of the total. In this case, we have 5 items, so the unit rate should be the fraction that represents 1 item out of 5.
The correct fraction that represents a unit rate in this case is:
Start Fraction 1 over 5 End Fraction.
To solve a ratio problem, you can use a unit rate, which is a ratio that compares a quantity to one unit of another quantity. In this case, we need to determine which fraction represents a unit rate.
Looking at the given options:
1. 127: This is not a fraction and therefore cannot be a unit rate.
2. 1/27: This fraction could potentially be a unit rate since it compares a quantity (1) to one unit of another quantity (27).
3. 3/4: This fraction is not a unit rate since it compares a quantity (3) to four units of another quantity.
4. 7/5: This fraction is also not a unit rate since it compares a quantity (7) to five units of another quantity.
5. 271: Similar to option 1, this is not a fraction and cannot be a unit rate.
Therefore, the correct option is Start Fraction 1 over 27 End Fraction, which represents a unit rate that can be used to solve a ratio problem.
